In Kirby's Dream Course, the second player plays as Keeby in multiplayer games, and he has identical abilities to Kirby. As he is not seen outside of Kirby's Dream Course's multiplayer mode, he is a somewhat obscure character in the Kirby series.

Yellow Kirby, a Kirby that looks very similar to Keeby, has appeared in Kirby series spin-offs and sub-games. Though they share the same color palette, they are not confirmed to be the same character.

Trivia

Keeby's coloration may be a reference to the fact that Shigeru Miyamoto initially wished for Kirby to be yellow, although HAL Laboratory eventually settled on Masahiro Sakurai's preference of pink.

In Japan, Keeby's name is spelled "Kībī" (キービィ). It is a portmanteau of the word for yellow (黄色 kiiro) and Kirby's name (カービィ Kābī).
